Is the Google integration using the Google Identity Service

[mark-ellul]

A couple of weeks ago I received an email from google

Hello Google Developer, You are receiving this message as a reminder that one or more of your web applications uses the legacy Google Sign-In web solution. Our announced plan stated that authentication support for the Google Sign-In JavaScript platform library will no longer be supported after March 31, 2023. After March 31, 2023, migration to the new Google Identity Services will be necessary to sign in customers using their Google Account to your platform. The SDK will use the new Sign In With Google client library.

I was wondering if HelloJS is using the Google Identity Service?

If not, what is the timeline of moving to use it?
